For this study, there were 453 subjects. They consisted of 119 positive schizophrenics, 122 negative schizophrenics and 212 normal people. They were asked to complete Zung's Self-Rating Depression Scale(SDS) and to perform one subtest, Digit
Symbol
of
KWIS(Korean Wechsler Intelligence SCALE). Subjects levels of depression were measured by the SDS. The level of psychomotor dysfunction was measured by Digit Symbol subtest of Korean Wechsler Intelligence Scale.

The results were as follows ; It was found that the depression level was higher in the negative schizophrenic patients than positive schizophrenic patients. Levels of depression were significantly higher in negative schizophrenics than positive
